Your fastest CPU would be a 1.4ghz Thunderbird (one hot little dude} with a BIOS flash. I think you need the KT-133A chipset to run anything in the XP family. Since the 1.4 is the fastest 200mhz chip prices remain relatively high. I would E-bay what you've got and upgrade to a more up-to-date platform. You're not going to get enough performance out of a CPU upgrade to justify the cost.
Abit IS7 - 2.8C @ 3.4ghz - Mushkin PC4000 (2 X 512) - Sapphire 9800Pro - TT 420 watt Pure Power
Samsung 120gb ATA-100 - Maxtor 40gb ATA - 100
Sony DRU-510A - Yellowtail Merlot
Here is what I recommend: open the window, and throw out the motherboard. Watch until a truck drives over it, then double check if its REALLY shattered, if it is toss the remaining pieces into your fireplace, well, you never know..
Then give the cpu to a friend, and pick up a new MB and CPU yourself. The KT133 was probably the worst chipset ever produced.

Some older boards couldn't even use the higher multipliers, he might be limitted to a 1.2GHz T-Bird!
